Answer:

Yes

Step-by-step explanation:

Becuase a statistical question is "one that can be answered by collecting data and where there will be variability in that data" you can collect data to find out

answer is no cause there will not be any variety, the data ask "which" also referring to "who" lives the farthest.

Please simplify the following trigonometric identity.

lesya692 [45]

Examining the question:

We are given the expression:

$\frac{1}{Sec(\alpha)-Tan(\alpha)}$

We know from Basic trigonometry that:

$Sec(\alpha) = \frac{1}{Cos(\alpha)}$

$Tan(\alpha) = \frac{Sin(\alpha)}{Cos(\alpha)}$

Simplifying the expression:

Replacing these values in the given expression, we get:

$\frac{1}{\frac{1}{Cos(\alpha)} -\frac{Sin(\alpha)}{Cos(\alpha)} }$

Since the denominator of both the values in the denominator is the same:

$\frac{1}{\frac{1-Sin(\alpha)}{Cos(\alpha)} }$

We know that $\frac{1}{\frac{a}{b} }$ = $\frac{b}{a}$ , using the same property:

$\frac{Cos(\alpha)}{1-Sin(\alpha)}$

and we are done!

The table in the lesson shows the number of sets of twins, triplets, quadruplets, and quintuplets registered at a twin conventio

Korolek [52]

Answer:

5494

Step-by-step explanation:

Assuming all members of each set registered, the total number is ...

2(2697) +3(29) +4(2) +5(1) = 5494

Since you're concerned with order of operations, perhaps you want to see the working out.

= 5394 + 87 +8 +5 . . . . perform all the multiplications

= 5481 +8 +5 . . . . . . . . . perform addition left to right

= 5489 +5

= 5494

Find the midpoint of the segment that has endpoints at (a+b, a-b) and (a, b).

Hunter-Best [27]

Answer:

((2a+b)/2 , a/2)

Step-by-step explanation:

The midpoint is the mean/average of both the x and y values.

Our x values are a+b and a

Our y values are a-b and b

The midpoint x value is (a+b + a ) /2 = (2a + b)/2

The midpoint y value is (a-b + b) /2 = (a)/2

The midpoint combines these two values to get ((2a+b)/2 , a/2) as our midpoint
